Are animals designed economically? The theory of symmorphosis predicts that the size of the parts in a system must be matched to the overall functional demand. In "Symmorphosis," Ewald Weibel show how animals as different as shrews, pronghorns, dogs, goats--even humans--all develop from essentially the same blueprint by variation of design. This is a hidden beauty of the animal kingdom, which can be uncovered by a rigorous investigation of the quantitative relations of form and function.
